Abstract: 1,254,783. Releasable fastenings. TINNERMAN PRODUCTS Inc. 27 Feb., 1969 [27 Feb., 1968], No. 10678/69. Heading E2B. [Also in Division F2] A panel engaging clip comprises a support member 12 and a resilient retainer member 14, the support member having two legs 18, 20 extending from a bight portion 16 for accommodating an apertured panel between them, the first leg 18 defining an aperture and the second leg 20 locating and having an opening 24 for insertion therein of the retainer member, the retainer member having a screw threaded aperture 57 which in the inserted position of the retainer member is opposite the aperture of the first leg, whereby in use of the clip screws pass through the aperture in the first leg, through the apertured panel and screws into the retainer member to clamp the support member in position on the panel. In the construction shown the leg 18 includes a pair of laterally spaced elongated arms 44 and 45 which extend upwardly and generally parallel to one another from the bight portion 16 and at their free end portions the legs are joined together by a bridge member 22 the opening 53 being defined between the bight portion, the arms and the bridge member. The bridge member shown includes an upstanding cylindrical pin 23 which after passing through an aperture 56 in the retainer member 14 is headed to form a rivet-like attachment for the retainer member. Instead of the pin being headed over, the aperture in the retainer member can be a smaller diameter than the pin and provided with a plurality of radially extending slits which define tabs which resiliently engage the pin; in a modification the pin can have a head so that it forms a stud engageable with a key hole slot in the retainer member; in a further construction an axially split headed stud can be provided which is engageable with a circular aperture in the retainer member. In a still further construction instead of providing a pin or stud, the end portion of the retainer member can be made U-shaped so that it embraces the bridge member; in this case the bridge member has a projection which engages a slot in the retainer member. The fastener device is either used for fastening two panels together by disposing 'both panels between the legs or alternatively one panel can be disposed between the legs and the other panel attached to the screw. The aperture 24 in the leg 20 can be made of smaller diameter than the screw so that it grips the screw frictionally.

Title: Process for fastening plates to iron sleepers by welding
IPC: B23K9/00
Filed: 1927-04-21
Abstract: 285,687. Siemens - Schuckertwerke Ges., Kuhl, L., and Ritz, C. April 21, 1927. Railway permanent way.-Tie plates are joined to iron sleepers by fusion welding, the plates and sleepers being pressed against each other by a ram or the like so as to ensure that the plates bear firmly against the sleeper throughout their whole surfaces, thus avoiding stresses in the joint when under load. When the joint is not situated in the neutral plane the pressure is such as to produce in the sleeper preliminary stress in the direction of the working pressure. The sleeper 13 may be lifted from the track 11 by levers 15 and transferred to a holder 12. The holder may be formed with shaped recesses to receive the sleeper, or with guide pins, or may be shaped to fit into the sleeper. The position of the sleeper above the holder is determined by stops 16 on the levers operated by levers 17. When the tie plate 19 and sleeper are in position they are pressed together either by forcing the ram 18 against the holder or by forcing the holder against a fixed abutment. After welding the stops 16 are withdrawn and the levers 15 raised to discharge the finished sleeper down the track 14 and to insert a fresh sleeper. The tie plates may be secured by hook-shaped grippers to the ram, or the ram may be magnetized or provided with an electric magnet. To avoid overheating when using several welding heads simultaneously cooling medium may be supplied to the ram or holder, a valve, opened or closed by movement of the ram or holder, being provided to cut off the fluid during the inoperative position.

Title: Electrical signal translating system
IPC: H03M5/00
Filed: 1954-04-13
Abstract: 740,060. Pulse code modulation circuits. STANDARD TELEPHONES & CABLES, Ltd. (Federal Telecommunication Laboratories, Inc.). April 13, 1954, No. 10838/54. Class 40 (5). Groups of pulses in the cyclic progression code are converted intc corresponding groups of simple addition binary code pulses by way of an intermediate code having digit pulses, of amplitudes dependent upon the pulse positions of the input code signal, each of which is algebraically combined with a pulse of constant predetermined amplitude. In the embodiment described, the unitamplitude pulses of the input fiveunit pulse groups, such as 10101, graph 25, Fig. 3, are applied from source 1, Fig. 1, through valve 2, to the input 17 of a short-circuit terminated delay line 3, of length equal to half a digit period. Due to the reflected sign-reversed output from the line, the voltage at point 17 becomes a series of pulses 30 of both polarities and of amplitude unity and twice and three times unity. These pulses are passed through valve 5 to a full-wave rectifier circuit 7 to produce the positive pulses 31 which are fed to the differential amplifier 8. The other input to amplifier 8 consists of corresponding positive double-amplitude pulses 32, derived from the timing generator 10 under control of the intermediate pulses in conductor 37 and the amplifier output 33 is fed to the full-wave rectifier 13 to produce the simple addition binary code output 35 which may modulate a radio transmitter 15. At the conclusion of each code group conversion, the line 3 is discharged through rectifiers 26 which are rendered conducting by the cessation of a biasing pulse 28 applied thereto, through transformer 27, from the generator 10.
